Here's a blast from the past: PENTHOUSE NORTH, the Joseph Ruben-directed thriller starring Michael Keaton and Michelle Monaghan. The flick was initially announced in the late summer of 2011, but we've pretty much forgotten about it since thanks to a lack of significant updates.

But looky here, an international trailer has shown up (good eye by The Playlist). It contains some spoilers, but overall the film doesn't look like anything we haven't witnessed before (especially if you've seen WAIT UNTIL DARK). The presence of charismatic leads of Monaghan and Keaton's stature might lend the film some credibility, though.

Sara Taylor (Monaghan), a photojournalist blinded in Iraq, is forced to play a deadly game of cat and mouse with the sadistic criminal Hollander (Keaton) – a man who will stop at nothing to get a fortune of stolen diamonds hidden in Sara’s penthouse apartment. Although Sara claims to not know where the diamonds are, Hollander utilizes psychological and physical torture in an effort to break Sara’s resistance. But Sara fights back. As the suspense builds to a shattering climax, Sara gains the advantage. But will it be enough to save her?

PENTHOUSE NORTH also stars Barry Sloane and Andrew W. Walker. Dimension Films holds the U.S. rights, so that could mean we're years away from seeing it here; however, it supposedly has a May 23rd release date in Russia.
